By

a sufiiciently great longitudinal force applied tothe strip 9, saidstrip may be moved so that the pin 14 is forced out of one of therecesses 17 against the force of the springi and is then by the force ofsaid spring causec to enter the other recess and hold the strip in theshifted position. The same detail of construction is clearly shown inFig. 3.

In Figs. 4 and 5 of the drawings is illustrated a modification of theinvention in which the abutments 11 for plain writing are dispensedwith, and individually and in-.

dependently changeable abutments 18 for cipher writing are employed inthe bases'of which is formed with a series of integralvertical'extensions or abutments 27, each of an average width in thelongitudinal direction of the bar equal to one-half the distance atwhich the key levers are spaced from one another, and spaced from oneanother by recesses of the same width. These recesses are slightlydove-tailed in a direction transversely of the bar. The extensions 27are used for writing ordinary writing with the -typewriting ke'ys, theirheights corresponding with the depths of the pro ections on the keylevers of the ordinary machine. The bar is at the front side reduced inthickness in its upper part, and in the top of the lower thicker portionof the bar is a'longitudinal groove 28, in which are received downwardextensions 29 from individually and independently changeable abutmentbodies 31 which rest upon the too of the thicker portion. of the bar,and have rearward extensions 32 which rest upon the top of the thinnerportion of the bar. these extensions 32' having rearwardly and upwardlyextending dove-tailed abutments fitting in the dovetailed intervalsbetween'ihe extensions 27. In order to prevent the rising of the abut-Tnents 33 from the bar 26 there is provided a long-key 34:, which fitsin recesses'formed. partly in the bar 26 and partly in the abutinentbodies 31. The key 3i at its end next the opening 10 is connected to ahandle 86,

"which is also connected to a short plate 87, ofthe same cross-sectionalform as the bar of the frame 3, which plate fits snugl 'y in thedove-taiied groove 24- in line with the bar; 7. Tosecure the plate 37 tothe bar 26, there ments d3, the whole bar 26 is removed from, themachine, the thumb screw is unscrewed,

so that the key 3d can he slid out of the recess, the abutment bodiesare removechand.

their positions changed, the partsare then replaced in position, thechange of the code has been effected. The bar 26 is slid longitudinallvand is retained in one of two positions; as before, to write ordinary orcipher writing by the pin 1% entering one of the recesses 17 insaid bar.

teferriirg to Figs. 10 to 15 of the drawmg, 4-1 indicates a bearingsecured upon the bar 7, through which passes'a tubular shaft 43, inwhich is a solid shaft 4-2. The shaft 42 extends beyond the shaft 43,.and around the shaft 43 is a tubular shaft 4L4; andaround the tubularshaft n is a tubular shaft 45. The shafts 42, 4.3, 44, t?) are rigidlysecured respectively to cylinders 46, 47, 4-8, 4.9.

Each cylinder is formed with a number, preferably ten, of grooves 51parallel with its axis, and in salt grooves are COlliZIllIlQd cipherstrips 52, an enlarged view of one of which is shown in Fig. 15. Thesecipher strips are in general construction similar to .the cipher strip9, but they are shorter, those on the shafts 42 and -l5 containingsixteen abutments, that is, eight'for ordinary, and eight for cipher,writing, and those on the shafts l3, 4% containing only twelveabutinents, six for ordinary and six for cipher writing. To shift thedevice for'writing cipher writing instead of brdinary, or con versely,there is provided a, lever 53, depending between the two cylinders tTand 48, pivoted at 5th, and formed near its pivot on opposite sidesthereofwith arms or projections -An arm 56, carrying a weight 57, swingson ,said pivot 54, and is adapted to rest on either of said. projections55, and, when so resting. presses the shafts and cylinders to the rightor left as the case may be.

Indicating marks 58' apprise the operator of the position of the weight,and therefore of the shafts and cylinders, and therefore whether the keylevers in their depressions are adapted to be arrested by the abutmentsof the strips for ordinary or cipher writing, On the ends of ,the shafts4:2, 43, 4 4:, 45 are secured wheels 61, (52, 63, 64 each formedon theright-hand sidewith notches 66 and to which extend spring arms 67secured to, and

extending outwardly from, the corresponding shaft. Said wheels may beturned with reference to the shafts by removing the springanms from thenotches, 66, said 'spring arms/then entering recesses 68 in the1efthand. when tlm of it sachet W.
